USED MAZAK QT6
The Mazak QT6 is a compact CNC turning center designed for high-precision production of small to medium-sized turned components. Manufactured by Yamazaki Mazak, the QT (Quick Turn) series is one of the most recognized CNC lathe platforms in the industry. The QT6 was engineered for shops that need fast cycle times, excellent repeatability, and a small machine footprint. Despite its compact size, the machine offers industrial-grade construction, reliable spindle performance, and the intuitive Mazatrol control system.
The QT6 is typically equipped with a 6-inch hydraulic chuck, an 8-station turret, and a high-speed spindle capable of up to 7,000 RPM. The machine generally provides approximately 8.7 inches of X-axis travel and 23.6 inches of Z-axis travel, with a maximum turning diameter around 11.8 inches and turning length up to 21.7 inches depending on configuration. Common spindle motor ratings are approximately 7.5 HP (5.6 kW), making the machine well suited for machining aluminum, brass, stainless steel, carbon steel, and engineering plastics.
Most Mazak QT6 machines are equipped with Mazatrol T-Plus, Fusion 640T, or EIA-compatible controls that support both conversational programming and standard G-code. Optional features may include tailstock, chip conveyor, tool presetter, bar feeder interface, and parts catcher.
Industries using the MAZAK QT6 include medical device manufacturing, aerospace, electronics, automotive, hydraulic component production, and precision contract machining. Typical parts include bushings, pins, fittings, valve components, threaded shafts, and prototype turned parts.
The MAZAK QT6 remains popular in the used CNC market because it combines Japanese reliability, easy programming, and excellent productivity in a highly compact and affordable package.
